9 Things You Can Give Up for Lent That Will Help the Environment

Cost: $14.98 for aluminum water bottle
Did you know that it takes 26 bottles of water to produce the plastic container for a one-liter bottle of water, and that doing so pollutes 25 liters of groundwater? Don’t leave a trail of plastic water bottles in your wake! Stop buying bottled water. Use reusable water bottles instead made from materials like stainless steel or aluminum that are not likely to degrade over time. If you choose a plastic water bottle, check the number on the bottom first: Plastics numbered 3, 6 and 7 could pose a health threat to you, so look for plastics numbered 1, 2, 4 or 5.

Each year, 19 billion catalogs are mailed to American consumers. All those catalogs require more than 53 million trees and 56 billion gallons of wastewater to produce -- and many of us don't even know how we got on so many mailing lists! So grab that stack of catalogs piling up on your coffee table and clear out the clutter. Visit CatalogChoice.org to put a stop to unwanted catalogs. Within 10 weeks, your mailbox will be empty of unwanted catalogs. A less cluttered mailbox means less pollution, less waste and less of the pollution that causes global warming.

The second biggest household energy user, after the refrigerator, is the clothes dryer. Overdrying your clothes can end up costing you money as well. (As much as $70,000 over your lifetime, according to the Green Cheapskate.) An electric dryer operating an extra 15 minutes a load can cost you up to $34 a year in wasted energy; a gas dryer, $21 a year. When using the dryer, clear the lint filter after each load and dry only full loads of clothes. Dry heavy fabrics separately from lighter ones, and don't add wet clothing in the middle of the drying cycle. And remember that hanging clothing outside in the sun and air to dry is the most energy-efficient method -- or use a folding indoor rack all year long.

Believe it or not, switching to recycled toilet paper can change the world. If every household in the United States bought just one four-pack of 260-sheet recycled bath tissue, instead of the typical tissue made from virgin fiber, it would eliminate 60,600 pounds of chlorine pollution, preserve 356 million gallons (1.35 billion liters) of fresh water and save nearly 1 million trees. And the best news is that a four-pack of recycled toilet paper costs about the same as a four-pack of conventional toilet paper.

No matter how you look at it, paper towels create waste. During your next trip to the grocery store, buy some reusable microfiber towels, which grip dirt and dust like a magnet, even when they get wet. When you are finished with them, toss the towels in the wash and reuse them again and again. They are even great for countertops and mirrors. When you absolutely have to use disposable towels, look for recycled products. If every household in the United States replaced just one roll of virgin fiber paper towels (70 sheets) with 100 percent recycled ones, we could save 544,000 trees.

Electric power plants are the country's largest industrial source of the pollutants that cause global warming. By snuggling under a blanket on the couch on a snowy winter night instead of turning up the heat, or enjoying the breeze from a fan in the height of summer instead of turning up the air conditioning, you can save pounds of pollution, as well as some money off your utility bills. Set your thermostat in winter to 68 degrees F (20° C) or less during the daytime and 55 degrees F (13° C) before going to sleep or when you are away for the day. And during the summer, set thermostats to 78 degrees F (26° C) or more.

Until recently, almost all dry cleaners used a cancer-causing chemical called perchloroethylene, also known as Perc or TCE. Traces of this toxic chemical remain on your clothes after dry cleaning and will evaporate into the air in your car or home. If you have to use a traditional dry cleaner, take your dry cleaning out of the plastic and air it outside or near a window before hanging it in your closet. To avoid the need for dry cleaning at all, make customer care a part of your clothing purchase decisions and choose fabrics that don't require dry cleaning at all.
